A merciful receive an infusion of 3 litres of a solution containing 234mg of sodium chloride?
(molecular weight = 58.5), 125mg of potassium acetate (molecular weight 98) and 21mg of magnesium acetate (molecular weight 142) How oodles meq of sodium, potassium, magnesium, acetate and chloride does the patient receive?
I don't even understand what this question is asking permit alone how to get to the answer.....
Answers:
Come now. Your patient is anyone given defined quantities of 3 compounds, the quantities being expressed contained by milligrams, and the question is how much he is receiving of each of the ions making up those compounds. The certainty that the answers have to be expressed in milliequivalents is a test of whether you realize the concept of equivalents. Basically 1 equivalent of sodium reacts with 1 equivalent of chloride; the actual weights in mg are relatebeside yourselfhe respective atomic weights. The atomic weight of sodium is 23, that of chlorine is 35.5 (giving the quoted molecular weight of 58.5), so the 234 mg of sodium chloride can be proportioned into sodium and chloride. What you have to do in a minute is find the equivalents of the other ions in the same way. There is the small difficulty near magnesium that it is divalent, so the equivalent weight is half the atomic weight, but I'm sure you can sort that out.
